The 2015 Latin-American School of High-Energy Physics will be held in Ibarra, Ecuador from 4 to 17 March 2015. The lectures will cover a broad range of HEP topics at a level suitable for students working for a PhD in experimental particle physics. Note that financial support may be available for Latin-American students attending the School. Although the School is targeted particularly at students from Latin-American countries, it is open to self-funding students coming from other regions.
Details and application deadline can be found here.
Rika Takahashi | 14 July 2011Worrying about blemishes on the skin is not just an issue for people who pursue personal physical beauty, but also for accelerator scientists. Scientists and engineers at KEK have found a way to deal with unwanted stains on the inner surface of superconducting cavities, which might be one of the causes of performance limitation.

30 June 2011Junior high school students in the Tsukuba area visited KEK for their school's job experience programme. Here they use a Kyoto camera to look for defects on the inside of an accelerating cavity.

Barbara Warmbein | 14 April 2011A small group of young researchers at DESY, Germany, is working on a robot that could drastically reduce the time it takes to optically inspect a cavity. Their work covers everything from the pure mechanics of the workbench and fine-tuned motors for moving the heavy parts to developing sophisticated methods of automatically analysing the pictures. Cavities might eventually pass the check in two hours instead of the one-and-a-half days it takes today.

Rika Takahashi | 9 December 2010Designing and fabricating an optimal accelerating cavity is not so simple. There are two important parameters scientists are looking for: the gradient of 35 megavolts per meter (MV/m) and the quality factor (Q0) of greater than 0.8×10^10. A Japanese cavity now fulfilled those requirements for the first time at a test which took place at the Superconducting radiofrequency Test Facility (STF) at KEK, adding momentum towards future mass production.

Rika Takahashi | 21 February 2008At the ILC, roughly 16,000 superconducting RF cavities made of pure niobium will accelerate electrons and positrons to the high energy of 500 GeV. Each one-metre-long cavity consists of nine cells, polished to provide micrometre-level surface smoothness and absolutely no impurities. The inside of the cavities need to literally sparkle since any surface blemishes or dust could cause them to lose their superconductivity, making them unable to sustain the electric field needed to accelerate particles. ILC scientists around the world are devoted to trying to get a higher yield rate for producing good-quality cavities by improving surface treatment methods and inspection procedures. A group of scientists from Kyoto University and KEK jointly developed the novel inspection system to take a close look at the interior surface of the cavities, and produced remarkable results.
